Abstract
1. Устройство для генерирования выходного стереосигнала, имеющего первый выходной канал и второй выходной канал, из входного стереосигнала, имеющего первый входной канал и второй входной канал, включающее в себя:генератор (110; 210; 340; 440; 640) информации о манипуляции, выполненный с возможностью генерировать информацию о манипуляции в зависимости от первого значения отсчета сигнала первого входного канала и от второго значения отсчета сигнала второго входного канала; иманипулятор (120; 220; 360, 370; 460, 470; 660, 670) для манипулирования комбинационным сигналом на основе информации о манипуляции для того, чтобы получать первый манипулированный сигнал в качестве первого выходного канала и второй манипулированный сигнал в качестве второго выходного канала;причем комбинационный сигнал представляет собой сигнал, полученный путем комбинирования первого входного канала и второго входного канала; ипричем манипулятор (120; 220; 360, 370; 460, 470; 660, 670) выполнен с возможностью манипулировать комбинационным сигналом первым методом, когда первое значение отсчета сигнала находится в первом отношении ко второму значению отсчета сигнала, или отличающимся вторым методом, когда первое значение отсчета сигнала находится в отличающемся втором отношении ко второму значению отсчета сигнала.2. Устройство по п. 1,в котором генератор (110; 210; 340; 440; 640) информации о манипуляции выполнен с возможностью генерировать информацию о манипуляции в зависимости от первого значения энергии в качестве первого значения отсчета сигнала первого входного канала и от второго значения энергии в качестве второго значения отсчета сигнала второго входного канала; ив котор�1. A device for generating an output stereo signal having a first output channel and a second output channel from an input stereo signal having a first input channel and a second input channel, including: a generator of information (110; 210; 340; 440; 640) about manipulation, configured to generate information about the manipulation depending on the first value of the signal count of the first input channel and the second value of the signal count of the second input channel; an manipulator (120; 220; 360, 370; 460, 470; 660, 670) for manipulating the combination signal based on the manipulation information in order to obtain a first manipulated signal as a first output channel and a second manipulated signal as a second output channel; moreover, the combination signal is a signal obtained by combining the first input channel and the second input channel; Moreover, the manipulator (120; 220; 360, 370; 460, 470; 660, 670) is configured to manipulate the combination signal by the first method when the first signal count value is in the first relation to the second signal count value, or different in the second method, when the first the signal count value is in a different second relation to the second signal count value. 2. The device according to claim 1, in which the manipulation information generator (110; 210; 340; 440; 640) is configured to generate manipulation information depending on the first energy value as the first count value of the signal of the first input channel and the second energy value as a second value of the reference signal of the second input channel; which
